FWIW, it's half way dark outside and I just tried my (old)Zeiss PRF.


Stepped out the front door and it instantly zapped grass/snow out to 500-600 yards(which is as far as there is grass/snow)....


Gave quick readings on houses at 1000-1200 yards.



Of course the unit is at balmy 6F ambient, I'm sure it wouldn't work at all when it is 0F.....

What battery does the Sig take?
